WILLIAM G. COOK, OF BUSHKILL, PENNSYLVANIA.

COMPOSITION FOR IMPREGNATING BELTS.

No Drawing.

To all whom it may concern:

Be it known that I, WILLIAM G. Coon, a citizen of the United States, residing at Bushkill, in the county of Pike and State of Pennsylvania, have invented. certain new and useful Improvements in Compositions for Impregnating Belts, of which the following is a specification.

This invention relates to compositions for impregnating fabric, and particularly compositions with which a fabric fan belt or other belt may be impregnated.

The general purpose of the invention is to provide a composition which permits a fabric fan belt to be used, and which will cause this fabric belt to resist the action of oil, but have good frictional. engagement with the pulleys or band wheels over which it travels to render the fabric belt somewhat elastic, and to increase its wear.

ll ith these objects in View, my improved composition consists of a mixture of linseed oil, gasolene, a drier of any suitable character, and whiting. These materials are heated and thoroughly mixed and then the fabric, either after, it is made into a belt or before, is soaked in this composition until it is thoroughly impregnated therewith. Then the fabric is dried.

The particular action of the various in gredients is that the linseed oil toughens the fabric and causes the fabric to be waterproof and oil-proof. The gasolene makes the mixture more penetrating than it otherwise would be. The drier performs the obvious function of causing the compound to Specification of Letters Patent. Patented B13 23, 1920, Application filed August 27, 1919. Serial No. 320,251.

dry quickly, and the whiting acts as a filler for the fabric and increases the frictional engagement of the fabric with the fan wheel or pulley over which it is disposed.

Preferably. I make the composition with the materials in the following proportions Linseed oil 5 gals. Gasolenet gals. Whiting- 5 lbs. An ordinary drier M 1 qt.

I claim l. A composition for impregnating fabric belts including the following 1ngrcd1ents 1n approximately the following proportions Linseed oil 5 gals. Gasolene at gals. VVh1ting 5 lbs.
